The Public Works Department is responsible for managing, inspecting, and cleaning the Sanitary Sewer System from the public mainline to Clean Water Services' wastewater treatment plants. Our team addresses trouble spots and conducts point repairs as needed.

Property owners are responsible for laterals, the sanitary lines that connect homes and businesses to the public system.

In rare cases, a sanitary line crosses private property lines, serves two or more tax lots, and has multiple connections.

In this case, the line is considered a public sanitary line and is the responsibility of the City to maintain.

For these public lines, the City requires a recorded access easement on each affected property for maintenance, inspection, or replacement.

A fixed charge, an average use charge, and a Local Service Fee (LSF) are all included on the City utility bill. They fund the Sanitary Sewer services provided to the Hillsboro community.

Visit our Utility Billing webpage to learn more about the charges on your bill.

Fats, Oils, and Grease (FOG) discarded down sink drains can lead to costly repair for property owners and block public sanitary sewer lines, causing overflow into streets, stormwater, and private properties. 

Prevent backups by properly disposing of FOG from residential cooking or commercial kitchens.
